If you've got good writing, don't overthink the visual components too much, imo. Rather than try to make them perfect, just focus on trying to do new and different things with each panel. You can do so many unique things with simple sprite manips, image editing, and other techniques. Also, the lessons about spacing and scaling and composition that come from spriting and staging scenes will prove beneficial if you choose to try drawing in a more traditional sense later on down the line.
